DevLog Darkroom vs Rollvane

DevLog is the all-in-one companion for film photographers who develop at home. Track every roll through its entire lifecycle, save the exact development recipe you used, log each frame's exposure data, and review your shooting and developing stats — all in one focused, offline app. From loading a fresh roll into your camera to archiving the final scans, DevLog keeps your analog workflow organized and repeatable. KEY FEATURES • Roll Lifecycle Timeline — Follow each roll through seven stages: loaded, shooting, shot, developing, developed, scanning, and archived, each with its own timestamp. • Development Recipes — Save your developer, dilution, temperature, time, agitation method, stop bath, fixer, wash, and a personal rating for every roll so you can reproduce your best results. • Frame Log — Record shutter speed, aperture, subject, and location for individual frames, so you never forget the shot. • Built-in Presets — Choose from a curated library of popular film stocks, developers, cameras, and lenses to fill in details fast. • Statistics — See your total rolls, rolls in progress, archived rolls, average development time, most-used film and developer, and a breakdown by film type. • 100% Offline & Private — No account, no network, no tracking. Everything stays on your device. Keep your darkroom knowledge in one place, roll after roll.

Build a three- or five-frame exposure bracket at a fixed aperture and record the complete sequence after shooting. HOW IT WORKS 1. Open Helper and tap Bracket. Enter the subject, lighting, aperture and anchor shutter. 2. Choose three or five frames and inspect the exposure offsets and available roll slots. 3. After taking the shots, explicitly confirm the completed bracket to add its frames to the active roll. Roll logs, the exposure helper, focus, filters and reciprocity references remain available. WHAT TO KNOW Calculated shutter times may not be supported exactly by your camera. Long exposures can require film-specific reciprocity correction. This does not trigger a camera or meter a scene. The complete bracket needs available frame slots; existing frames are preserved. iPhone and iPad.
